This invention relates to an improvement in clearer? roll foriniin mechanisms, pa!' tienlaily :Hlilljltvl tor use. :1 connection with high speed cigarette niachinms ot the continuous roll th iierctol'orc in machines of this type it: has been customary to shower shredded tobacco into a trough. the bottom of which formed by a moving; belt and the side walls of which in some instances are also formed oi niovin-g belts. in such machines the tobacco is pushed across a bridge at the end oi the trough onto a moving: strip of wrapping paper supported b v a second m ving heh whieh run through a rod ll win ng tube. he particular function oi" which is to curl the wrapping paper up around the tobacco lvii g thereupon zunl to coinnress the tobacco into a clo ed continuous ltltlin ordinary cigraiette. ma hines ot' the chi \\'ell-l-;no\vn type. thetraveling betts forming the bottom and side walls of the trough were the cause of considerable trouble in the operation of the machine. inc reason for this trouble vas the excessive Wear due to the constant grinding ot' the bells which was caused by the gritty substances in the tobacco itselt. Another cause was the (lilliculty in evenly iransierriiu: the tobacco fr m the trough across the bridge into the rod forming tube. lln high speed machines these (lllllx'lllilt,-l are more i rouounced than in the old welllinon'n machines. for obvious reas ns.

The main object oi. the presentinvention is the production of a cigarette ro l forming machine which is entirely free fro the letcets of the old t'aveling trough mechanisms.

A further object is the nronlutuion ot a levice in which the serious defects ot' the older machines are eliminated and in which the tobacco is showered directly upon the strip of wrapping paper in which it to be a'ttoi \varvl inelosed.

Still another object is the production of i r aoovo men- 1 is led over a LEM.

where it receives the shower of tobacco and then, at a position beyond and in alineinent with the runway, curled up a round the. tobacco and seated to form closed continuous rod.

With these and other objects not specifieall v mentioned in view. the invention consists in certain constructions and eoinbinations which will be hereinafter i'ull described and then specifically set forth in the claims hereunto appended.

in the ;l(.'COll1f)flD VlI1 2' drawings which t'orm a part of this specification and in which like characters of reference indicate the same or like parts, Figure 1 is a plan, view of one end of a device constructed in llt'ttlltlfllltt with the ii'ivt-ntiong Fig. 2 is a Slllt elevation of the structure shown in l igr. 1: Figs. 3 and 4 are respectively extension ot' the structures shown. in Figs. 1 and '3: Fig. 5 is a sectional view taken on the line 5 in Fig. 1 and enlarged; and Fig. 6 is an enlarged perspective view of the t0- haeco reee vine trough and sectioned at the line 6 in Fig. 1.

in cari vin; the invention into etl ect. there is providv'wl a run vav along which a strip of wrapping paper is drawn. said runwa; being adapted to guide a shower of tobacco directly upon the u raniiing paper Within which it; is to be afterward inclosed. There is further provided means for compacting the tobacco on and inclosing it Within the wrapping); paper to form a closed continuous rod. In the best constructions, a straight runvvav will be employed which cooperates with means beyond and in alinc-raent therewith tor cmnpacting the tobacco and hidesinc; it Within the wrapping paper to form a closed continuous rod. This runway and inelosing means may vary in construction within wide limits.

It is to be understood that the devic The bracket 2 supports two pairs of integral tansversely extending arms 3,3 and 4, 4. Each arm 3 is connected with the adjacent arm 4- by means of a pintle Mount ed to slide and rotate upon these pintles are arms 6. Two of these arms are integrally connected with a casting 7 which extends along the greater part of the length of the bracket 2 and forms the front side wall of a trough of which the operating face of the bracket 2 is the bottom. Similarly, the other two arms (3, (3 are integrally connected with a similar casting S, forming the rear side wall of the trough before referred to. The function of this trough is to guide a shower of tobacco upon a strip of wrapping paper running along the upper operating face of the bracket 2 between the side walls 7 and 8 and otherwise unsupported, the operating face of the bracket forming a runway for the paper. For the purpose of guiding the strip of wrapping paper running through the runway against lateral displacement, the adjacent lower edges of the castings 7 and 8 are'rabbeted respectively at 9 and 10 so that the extreme edges of the strip of paper run under the upstanding portions of the castings 7 and 8 and do not receive tobacco and are left clear so that they may later be folded around the tobacco and seamed. At the extreme end of the bracket 2 is a smaller bracket 11 carrying a roller 12 over which the paper is led through the runway it being understood that the paper comes from a reel suitably mounted in the machine in a wcll-known manner. The castings 7 and S are swingable upon the pintles 5 and are also capable of longitudinal movement thereon. The purpose of this construction is to enable the operator of the machine to swing them out of the way, thus exposing the entire upper surface of the bracket 2 for cleaning or other purposes. \Vhile the machine is in operation, however, the castings 7 and 8 are securely locked in operative position. This result. is effected in the following manner. Each of the arms 6 is provided with a notch 13 and between each of the arms (3 and the adjacent arm 4 there is located a collar l-t having a lug or projection 15 adapted to engage the notch 13 before referred to. Each of the collars 14: is loosely mounted upon the pintles 5 andccach has a dependent lu r 16 through which is threaded a screw 1, bearing against the bracket 2. To lock the castings in operative position, they are swung down into contact with the operating surface of the bracket 2 and moved longitudinally upon their respective pintles until the notch 13 engages the projection 15 of the operating collars 14. The screws 17 are then operated to cause a slight rotary movcment of the collars l4 and projections 15, which results in firmly holdingthc castinszs in operative position. The castings 7 and 8.

extending bosses it. 25, which bosses are journalcd upon a sleeve 26 Fig. 5). This sleeve 26 is held in position within a support .27 by means of a set. screw 28. The support '27 is formed integrally on a bracket 28 which carries two other supports 29, 30,-

th axes of which are in alinement with the axis of the support 27. Within the supports 2! 30 and also within the sleeve 26 is journalcd a shaft 3 linncd to this shaft is a gear 32 in mesh with a similar gear 33 fast upon the shaft 20 before referred to. i\. spiral gear 34 also secured to the shaft 31 and this spiral gear is in mesh with a second gear 35 fast upon a shaft 36 extending downward through a long bearing 37 and carrying upon its lower end a beveled gear 3?. which beveled gear is in constant mesh with a bevel pinion 39 fast upon and rotated by a shaft 40, which shaft is or may be one of the main power shafts of the machine. The peripheral speed of the presser wheel 19 is approximately equal to the speed of the strip of wrapping pape' and the tobacco carried thereby which passes under the presscr wheel. The presscr wheel compacts the tobacco to a predetermined extent which may be varied by adjusting the bracket 23 to vary the relative vertical positions of the trough and presser wheel. This adjustment is effected by means of a set screw 41 threaded in the bracket 28' and bearing against the bracket 23 to the right of the shaft 31 (see Fig. 1).

Beyond the extreme left end of the trough is a bridge 42 over which the paper carryin; the. tobacco r'uns. This bridge is supported by a bracket 43 suitably supported by the bed ofthe machine. The bracket may be adjusted laterally in an obvious manner hyineans of the set screw 44 and held in adjusted position by means of the thumb-screw 45. After the paper carryin; the tobacco has passed over the bridge 42, it enters the rod forming mechanism proper which operates to fold the wrapping paper around the tobacco and seal the same to form a. closed continuous rod. This'rod forming mechanism includes a rod forming tube generally indicated by the numeral 46 and constructed and operated in a wellknown manner. Since the specific construc- ,tion of this rod forming tube lies beyond the present invention and is well known in the art, a specific description thereof is Omitted. .lt may be remarked, howev r, that coiiperatinp with the tube is an endless beit 4'7 driven by a pulley 48 and passing over a gripping wheel 49 and adjusting rollers 50 and through a suitable guiding moon,- nism 51 and over a suitable guiding roller 52 located at the entrance of the rod form ing tube and under the bridge e2 bet'orc ferred to. The pulley 48 derives its motion from a shaft upon which it is mounted. This shaftis journaled in a suitable bearing 5 carried by the bed 1. Upon its rear end is mounted a worm wheel 54- which in mesh with a worm 55, which worm is fast upon and driven by the power shattt0 before rcferred to. 20. A pastingwheel torining, a part of a pasting mechanism for securing, the edges of the wrapping paper together is indicated by the broken circle at 5!), and a scannnp belt the function of which is to press the pasted seam together to cause the pasted edges to adhere firmly is indicated at 57 by the broken circles and lines.

The parf ticular construction of the pasting ll'lit'lm nism and seaming device lies Wholly beyond the range of the present invention, and a detailed description thereof is thcretorc omitted. By an inspection of the drawings,

it will be readily understood that the runway for the wapping paper is a straight runway and that, the rod forming" incchanisnr proper hes beyond said runwayand 1n alinement therewith.

it will be readily uiidcrstood also thatthe tobacco is not disturbed; after it is originally showered upon the 40 moving paper in the trough formed by inc bracket 2 and the castings 7 and, 8, civccpt to be compacted and formed into the shape of the finished cigarette rod. In Words, it is not; advanced by one means and transferred to a second advancing means, as

other is the case in the machines well known in the art; butit is showered directly upon the paper in which it is afterward inclosed.

In view of the foregoing. a detailed dcscription of the operation of the device isdeemed unnecessary to a full understanding of the invention and such description is therefore omitted.
